For Kenworth W900B trucks with large radiators, the Herd Big Tex 4 Post Aluminum Grille Guard is designed as a heavy-duty solution that combines front-end protection with a polished appearance. Built from aluminum, this grille guard features an 18-inch extruded bumper, four oversized fully boxed-in uprights, and 4-inch horizontal tubes intended to provide structural rigidity and help protect the grille and front components from road debris. Standard features include impact plates, side and center eyebolts (on select configurations), light mounting tabs, and Herd's mirror-polished finish. Some versions are available with options such as a lower rake design or Slam Latch functionality, while other configurations may be offered without lift assist or light cutouts depending on application needs. This grille guard is sold individually as a high-quality aftermarket replacement rather than an OEM part. A manufacturer warranty covers defects in materials and workmanship, and the product typically ships directly from the manufacturer. As with most fitment-specific truck accessories, verifying the correct mounting pattern and compatibility before purchase is recommended to help ensure proper installation.
